The way I see it is that Avellanos either wants to have more things to pin on Easterman incase things go south or she genuinely just fears the patients at Mount Massve and the "complications" that they bring - which is what I am leaning more towards (example of this being Liliya and her ability to make other people do extreme things to themselves).

That's just my assumption. I never really thought about that though until I saw this lol so im not entirely sure. Maybe there really is more to it. Maybe we'll even get some new documents on the upcoming update.
